7+3+5 Think 3+5 =8
10+5 Think 7+3 =10
We have been working on automatic recognition with doubles. During the day we practice doubling numbers and call out numbers 1-10 asking students to double the number.
You can practice this at home. If your child has mastered 1-10 you can do 11, 12, 25, 50, and multiples of 10.
Cross number puzzles
Students are practicing finding sums to 12-20. Students are using their addition and subtraction strategies to find the missing addends. We are also using tens frames and Cuisenaire Rods to help us break apart these bigger number combinations.
